[IGSMAIL-8576] PolaRx5 firmware 5.6.0 available

[Peter.Steigenberger at dlr.de]

Dear colleagues,

Septentrio has recently published a new firmware version 5.6.0 for its PolaRx5 receiver which is widely used in the IGS network. From a multi-GNSS perspective, this firmware offers important new features:

* QZSS L1 C/B signal tracking: starting with QZS-6 launched in February this year, all future QZSS satellites will not transmit an L1 C/A signal anymore but switch to L1 C/B. Please note that also no L2 signal will be transmitted anymore.

* Support of QZSS PRNs J08-J10: QZS-6 will use J08 and signal transmission is expected to start soon. QZS-5 and QZS-7 using the other two PRNs are expected to be launched at the end of 2025 and the beginning of 2026, respectively.

* NavIC L1 tracking: starting with the NavIC satellite NVS-01 launched in May 2023, an L1 signal is transmitted in addition to L5 and S band.

The new firmware and the release notes are available at https://www.septentrio.com/en/products/gnss-receivers/gnss-reference-receivers/polarx-5

Direct download link for the firmware: https://www.septentrio.com/resources/PolaRx5/PolaRx5_fwp_5.6.0.zip

We would like to encourage to install this firmware to support the signals and satellites mentioned above. This firmware also supports the latest RINEX version 4.02 for receiver-generated RINEX files and we encourage to switch to this version for IGS file submissions.

Thanks for your support and best regards,

Markus Bradke on behalf of the IGS Infrastructure Committee
Peter Steigenberger on behalf of the IGS Multi-GNSS Pilot Project
